I'm concerned with clearances with my planned setup, and wondering if there were any machining or clearances that need to be addressed:

GSR block
LS crank
LS rods
PCT pistons

The ls crank and rods, will give me the same compression as the gsr rods and crank with the PCT pistons. Just wanted a few extra cc's cuz its cheap.

Have never gotten straight answers about PCT pistons in gsr's and if its streetable...running 91 octane?

For anyone wondering about the head...I'm thinking Buddy Club IV's and the full head package

 

PCT with ls stroke will be nearly 13:1.The P30 is a better choice at around 12:1.The ls rods would have to be narrowed for the PCT pistons to fit.

...but not narrowed to fit the p30's?

 

man there has been many topics of this and i have done it my self,
94 gsr block
99 ls crank
99ls rods
CTR(pct) pistons

13:1 c/r

ls vtec the right way no external oil line..

i didnt get a chance to dyno it i sold it before i could tune the motor, but the motor pulled strong.. but of course you want to use ls rod and crank bearings,
make sure everything is spining freely... bend the oil squirter a lil bit so they dont hit the crank.


but i would guess it shoulda been around 190 with ctr cams... may be more but its all in the tuning..
